PROTECTOR MECHANlSM FOR LOOMS.

Patented Dec. 1 1, 1906.

Application filed July 7. 1905. Serial No. 268,631.

T 0 all whom it may concern:

Be it known that 1, CHARLES WESLEY lli'rics, of St. llyacinthe, Province of Quobcc, Canada, have invented certain new and useful Improvements in Protect-or Mechanism for Looms; and I do hereby declare that the following is a lull, clear, and exact description of the same.

M invention has for its object to enable the orward beat of the lay to be shortened through the medium of the dagger when the shuttle fails to enter its box, thus making such shortening action more prompt than heretofore; and a further object of the invention is to simplify and reduce the wet ht of this high-speed mechanism,and there yobviate or reduce the breakage hvrctofore frequently experienced.

The invention ma be said, briefly, to consist of a displaceab e device connecting the initial operating means of the lay to the lay ands member coacting with the dagger for displacing such device and shortening the forward beat of the lay when the shuttle fails to enter its box.

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part of this specification, in which similar reference characters indicate the same parts, and wherein- Fi ure 1 is a side elevation of a loom provided with my invention, partly in section. Fi '2 is a plan view thereof. Fig. 3 is a detafi horizontal sectional view of my im roved means for automatically shortening t e forward beat of the lay, the section being taken on line A A, Fig. 4. Fi 4 is a part side elevation and part vcrtica sectional view, the sectional view being taken on line B B, Fig. 3. Fig. 5 is a perspective view of the sheath carried by the dagger and constituting the initial 0 erative part of my improved mechanism. lg. 6 is a side elevation of my improved collapsible pitman. Fig. 7 is a plan view thereof, and Fig. S'an end view.

The frame I) of the loom, the crankshaft 0, the lay d, the lay-sword e, the rotectordagger f, the protector-shaft g, an the shuttie-boxes k may be of any preferred type and constructed and arranged as usual.

M invention relates to the rotector mec ianism, and it has particular re erence to the pitman i, which connects the crank to the lay-sword, and means carried by and actingv in conjunction with the dagger forcausing the forward beat of the lay to be shortened.

According to my invention the protectorda ger f is collapsible in that it carries slidabl y a sheath consisting of a metallic plate formed to iresent a pair of straight lingers 1:, one at eac side of and adapted to proect slightly beyond the forward end of the dagger, and a curved linger m, ada led to partially encircle the protector-shall. g, with its end proieeting between such shaft and the lay d,while the sides n of the plate are slotted, as at n, and bent down to overlap the sides of the da ger. The sheath thus constructed is secured slidably to the dagger by a pair of headed studs p, thus providing a collapsible protector-dagger of telescopic construction. ihe lay d has a through, withits smaller end adjacent to the protector-shaft and its larger end in close proximity to the lugs-s upon the sword and through which the pitman 'i is connected to the sword. An oscillatory slide-rod t lies in the tapered hole 1' in position to have its lower end project through the hole and rest normally in contact with curved'finger m, and its upper end is pivotally connected to a slide-rod 11., which is caused to actuate a latching-plate and allow the pitinan to collapse, and thus shorten the forward beat of the lay.

My improved pitman consists of a prefer ably wooden bar 2, preferably recta ular in cross-section and ivotally connected to the wrist 3' of the cran shaft 0 by a metallic band 4, secured to one end of the bar by a bolt 5. This wooden bar is inserted into one end of a metallic sleeve 6, conforming in cross-section to it, the opposite end 7 whereof is cast solid and tapered and formed with a concavity, by means of which and a metallic band 8, a bolt 9 for securing such band in place, and a pin 10 such end is pivotally connected to the lugs 8 upon the lay-sword. The bar is free to slide to and fro in the sleeve; but the extent of its movement is limited in one direction by the solid end 7 and in the opposite direction by a shoulder 12 and an inwardly-projecting e 13, diminishing the open end of the sleeve, such shoulder being formed bya diminishment of the cross section of the portion of the bar adjacent the crank, this diminished portion also accommodatin the movement of the sleeve and bar relative y to oneanother while the pitrnan is collapsing or being drawn out. A portion of the top of the sleeve 6 is removable and held in place by screws 60, and the object thereof is to enable tapered hole 1' out therethe enlarged end of the bar to be set in place or removed.

The means for retainin the pitman in their extcn ed condition consists of a stop ing-plate 20, hinged at one end to one on of a longitudinal opening in preferably the top side of the sleeve, such plate being arranged to extend transversely to the sleeve and in close proximity to the end of the bar 2 when the pitman is extended and with its free end projecting into an open ing 21 in the under side of the sleeve. The stopping-plate is displaceabl' held in this position by a latchin -plate 22, before mentioned, secured rigid y at one end to a rod 23, pivotally mounted in a pair of lugs upon the under side of the sleeve, such latching-plate when raised fitting into the opening 2] in position to engage the lower end of and retain the stopping-plate. A lever-arm 25 15 mounted ri idly upon the rod 23 and projects u war ly alongside of the sleeve, and it is yiel ingly held in position with the latchin -plate in the opening 21 by a retraetile he 'cal spring 26, connected between its upper end and a rigid e e Ihe lever-arm 25 an with it the latchinglate 22 are displaced to remove the latter om its engaging position, and thereby releasing the stopping-plate and allowing the pitman to collapse or telescope, by means of the before-mentioned slide-rod it, which bears upon the lever-arm 25 and the means for actuating the same. The stopping'plate 20 is yieldi 1y retained transversely to the sleeve 6 by a ow-spring 35,secured at one end to the top of the sleeve and curved around the fulcrum-point of such plate 20 with its free end bearing upon the said plate.

Operation: The operation of my improved protector mechanism is as follows: When the shuttle enters its box properly, the pitman will remain extended and will erform the usual function of actuatin the av, and the protector-daggers are disp acecl from alinement with the buffers carried by the breastbeam, also as usual. It is when the shuttle fails to enter its box properly and remains on the raceway and the forward beat of the lay if not shortened would cause damage to the warp in the loom that my improved mechanism comes into play. When this condition obtains, the protector-dagger (as usual) strikes the protector-lever upon the breastbeam and causes the belt to be thrown off, thereby sto ping the loom. The fingers k strike just before the da ger, thus causing the sheath to slide upon 51c dagger and the curved finger m to force the slide-rod t up wardly in the hole 1', which slides the rod u and moves the lever-arm 25, and conseuently depresses the latching-plate 22, with t e result that the stopping-plate 20 is freed and the bar 2 is released.

the members of The pitman then telescopes, and the forward beat of the iay 1S 27 upon the sleeve.-

.protector-dagger, the lay,

shortened. After the shuttle has been replaced and the loom started the pitman will e again extended, the stopping-plate being forced by the bow-spring into position to be engaged by the latching-plate, which will meanwhile have been raised by the coiled spring, and such spring simultaneousl will have caused the rods t and u and the slieath to be returned to their normal positions.

It is obvious that the dagger and sheath together constitute a telescopic or collapsible )rotector device, upon the telescoping or colapsing of which the pitman is collapsed and the forward beat of the lay shortened, which action takes place slightly in advance of the action of the dagger proper.
